Rich Wilde and the Tome of Madness

Rich Wilde and the Tome of Madness is a 5x5 cascading-grid slot from Play'n GO, set in the Cthulhu mythos and built around cluster wins of four or more matching symbols. Each winning cluster adds charge to the portal, which can trigger feature effects as the round continues.

The game includes a Special Wild, the Tome of Madness, which can replace HP and LP symbols, and a Multiplier Wild version of Rich Wilde that can double win values. As the portal fills, additional features may activate, including Abyss and Void effects that remove symbols from the grid and contribute further charge.

When 42 winning symbols are collected, the Other World free round begins. In this bonus round, portal effects are applied after cascades, and eye symbols can open to release the Mega Wild Cthulhu symbol. The demo version is available to play for free, allowing users to practice before playing for real money.
